Monitoring:

• A pulse oximeter is a device that measures the amount of oxygen in your blood. A cord with a clip or sticky strip is placed on your finger, ear, or toe. The other end of the cord is hooked to a machine.
• Telemetry is continuous monitoring of your heart rhythm. Sticky pads placed on your skin connect to an EKG machine that records your heart rhythm.
• Arterial blood gas (ABG) measures how much oxygen and carbon dioxide are in your blood.

Tests:

• Blood and urine tests will show if you have an infection. These tests can also give information about your overall health, such as kidney function.
• An EEG records the electrical activity of your brain. It is used to find changes in the normal patterns of your brain activity.
• A CT scan or an MRI may show abnormal areas in your brain. You may be given contrast liquid to help the areas show up better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have anything metal in or on your body.

Treatment:

Oxygen may be given if your blood oxygen level is lower than it should be. You may need a ventilator. A ventilator is a machine that gives you oxygen and breathes for you when you cannot breathe well on your own. An endotracheal (ET) tube is put into your mouth or nose and attached to the ventilator. You may need a trach if an ET tube cannot be placed. A trach is a tube put through an incision and into your windpipe.
